Unfortunately this is impossible to achieve.
Unless you can guarantee that the same physical pieces of disk are going to
always be mapped to the same parts of the RBD device then you will leave data
lying around on the array. How easy it is to recover is a bit of a question
about how valuable t

As Darren replied while I was typing this, you can't have dangerous
data written all over a cluster which automatically moves data around,

Hi,
can you paste the following output?
# ceph config-key list | grep grafana
Do you have a mgr/cephadm/grafana_key set? I would check the contents
of crt and key and see if they match. A workaround to test the
certificate and key pair would be to use a per-host config [1]. Maybe

Hi Ceph users,
We have 3 clusters running Pacific 16.2.9 all setup in a multisite
configuration with no data replication (we wanted to use per bucket policies
but never got them working to our satisfaction). All of the resharding
documentation I've found regarding multisite is centred around m
Hi,
sorry for not responing earlier.

pinning. I quickly googled it and saw it was a new feature in Luminous. We

Hi,
I wonder if a redeploy of the crash service would fix that, did you try that?

Curious if anyone had any guidance on this question...

Dear Ceph folks,
In a Ceph cluster there could be multiple points (e.g. librbd clients) being
able to execute rbd commands. My question is that , is there a methold to
reliably record or keep a full rbd command history that ever being executed?
This would be helpful for auditors as well as for
Thank you for the answer, that's what I was looking for!

Hi, we have a ceph 17.2.6 with ragosgw and a couple of buckets in it.

After few backups we got
